Displaying Internet files
The network must ensure protection against viruses and
malicious software. The same applies to access to the
Internet or other networks.
The protective measures for this network are the
responsibility of the machine tool builder and the
respective network administrator, for example through a
firewall.
Proceed as follows to open Internet files with the extension htm or
html directly on the control:
Call the file manager: Press the
PGM MGT
key
Select the directory in which the Internet file is
saved
Move the cursor to the Internet file
Press the
ENT
key
The control opens the internet file in its own
application using the
web browser
tool.
With the key combination ALT+TAB, you can always
return to the control's user interface while leaving the
browser open. Alternatively, you can also click the
corresponding icon in the task bar to switch back to the
user interface of the control.
If you position the mouse pointer over a button, a brief
tool tip explaining the function of this button will be
displayed. More information on how to use the
web
browser
is provided under
Help
.
After starting the
web browser
, it checks at regular intervals
whether updates are available.
You can update the
web browser
only if you deactivate the
SELinux
security software during this period and if a connection with the
Internet is available.
Reactivate
SELinux
again after the update.
